[mesa-users] Profile name zero padding

[Robert FARMER]

So I have this python library for reading mesa files, taking care of
reading the profiles.index:

Run as:
import readMesa as mp

m=mp.MESA()

m.loadProfile(num=MODEL_NUMBER)
#or
m.loadProfile(prof=PROFILE_NUMBER)

#and then there is an iterator:
prof_iter=m.iterateProfiles()

#iterator can also take a model number range as:
# m.iterateProfiles(rng=[min,max])
#or give it a list of priorities as:
#  m.iterateProfiles(priority=[1,2,...])

for x in prof_iter:
#Note the data is returned in the m class not in x!
    m.prof_dat[]

The main data is in m.prof_data["COLUMN_NAME"] and the header is in
m.prof_head["COLUMN_NAME"]

Hope it helps
Rob
